Small Methods, Volume 10, Issue 11, 8 June 2026.Full van der Waals graphene/h‐BN Hall bars with atomically perfect interfaces enable thickness‐tuned dielectric shielding. Varying h‐BN thickness (11 and 22 nm) switches quantum interference between weak anti‐localization and weak localization, achieving phase‐coherence lengths enhancement while maintaining spin coherence.

Anomalous transport in Kane fermions
, 2021 Kane fermions are characterized by a linear Dirac cone intersecting with a flat band, resembling a pseudo-spin-1 Dirac semimetal. Similar to relativistic Dirac fermions, Kane fermions satisfy a linear energy-momentum relation and can be classified as ...

Microscopic study of vorticities in relativistic chiral fermions [PDF]
, 2015 It is usually believed that unlike the external magnetic field which one can set directly, vorticity is a property of the flow of particles, which is indirectly controlled by external fields and initial conditions.

Electronic Properties of Curved Few-Layers Graphene: A Geometrical Approach
Condensed Matter, 2018 We show the presence of non-relativistic Lévy-Leblond fermions in flat three- and four-layers graphene with AB stacking, extending the results obtained in Cariglia et al. 2017 for bilayer graphene.

The Phase Diagrams of the Schwinger and Gross-Neveu Models with Wilson Fermions
, 2007 Introduction There has recently been considerable discussion on the phase structure of theories with Wilson fermions. A system of free Wilson fermions exhibits a second order phase transition at = 1=2d, being the hopping parameter and d the ...

Anomaly-free sets of fermions [PDF]
, 2005 We present new techniques for finding anomaly-free sets of fermions. Although the anomaly cancellation conditions typically include cubic equations with integer variables that cannot be solved in general, we prove by construction that any chiral set of ...

Universal relations for disordered systems
New Journal of PhysicsThe universal relations for spin- $1/2$ fermions with contact interaction in the presence of quenched disorder are discussed. The disorder is modeled by a random external potential with the Gaussian distribution and δ -like two-point correlation function.

Fermions and Emergent Noncommutative Gravity
, 2008 Fermions coupled to Yang-Mills matrix models are studied from the point of view of emergent gravity. We show that the simple matrix model action provides an appropriate coupling for fermions to gravity, albeit with a non-standard spin connection ...

Four-Fermion Dynamics and Fermion Masses [PDF]
Progress of Theoretical Physics Supplement, 1996 Four-fermion operators with large anomalous dimension may feed down mass to quarks and leptons from a heavy fourth family. No technicolor sector is required. A model illustrates the origin of the large top mass along with quark mass hierarchies and mass mixings.
